摘要:
A method of manufacturing a nicotine delivery product comprising nicotine and a cation exchange resin. More precisely, to a method for preparing a nicotine delivery product said method comprising (a) mixing nicotine, a cation exchange resin, an organic polyol and water to form a mixture wherein the total amount of water is from 26 to 45% by weight of the total mixture, and (b) removing water from the mixture to produce said nicotine delivery product.
摘要:
The invention relates to a method of relieving nicotine craving comprising the steps of providing at least one chewing gum comprising tobacco alkaloid to a user, providing relief of nicotine craving to said user by transferring of tobacco alkaloid from the chewing gum to the human body of said user by chewing of said chewing gum, said chewing of said chewing gum comprising a chewing process involving a transfer of tobacco alkaloid from said chewing gum above a threshold transfer rate in the period of about ½ minute to about 2½ minutes from initiation of said chewing process.
摘要:
A nicotine delivery product comprising the reaction product of a nicotine/cation exchange resin complex and an organic polyol; and a method for preparing it comprising (a) mixing an aqueous suspension of a nicotine/cation exchange resin complex with an organic polyol or an aqueous solution thereof, and (b) removing water from the mixture to produce said nicotine delivery product. The nicotine delivery product has a nicotine release rate of at least 80% over a 10 minute period. It is particularly suited for use in smoking substitution devices delivering nicotine such as chewing gum, patches, lozenges, melting tablets and tablets for chewing.
摘要:
The inventors have modified the amino acid sequence of a maltogenic alpha-amylase to obtain variants with improved properties, based on the three-dimensional structure of the maltogenic alpha-amylase Novamyl. The variants have altered physicochemical properties, e.g. an altered pH optimum, improved thermostability, increased specific activity, an altered cleavage pattern or an increased ability to reduce retrogradation of starch or staling of bread.
摘要:
The present invention relates to a phytase which has at least 80% identity to a phytase derived from Citrobacter braakii and comprises at least one alteration when compared to this phytase. These phytase variants have amended, preferably improved, properties, such as thermostability, temperature profile, pH profile, specific activity, performance in animal feed, reduced protease sensitiliby, and/or an amended glycosylation pattern. The invention also relates to DNA encoding these phytases, methods of their production, as well as the use thereof, e.g. in animal feed and animal feed additives.
摘要:
The present invention relates to hybrid polypeptides having a first amino acid sequence having endo-amylase activity and a second amino acid sequence having carbohydrate binding activity. The present invention also relates to the use of the hybrid polypeptides in starch processing and baking.
